MapboxDirections.swift makes it easy to connect your iOS, macOS, tvOS, or watchOS application to the Mapbox Directions API. Quickly get driving, cycling, or walking directions, whether the trip is nonstop or it has multiple stopping points, all using a simple interface reminiscent of MapKit’s MKDirections API. The Mapbox Directions API is powered by the OSRM routing engine and open data from the OpenStreetMap project.

Despite its name, MapboxDirections.swift works in Objective-C and Cocoa-AppleScript code in addition to Swift 3.

MapboxDirections.swift pairs well with MapboxGeocoder.swift, MapboxStatic.swift, MapboxNavigation.swift, and the Mapbox iOS SDK or macOS SDK.

Getting started

Specify the following dependency in your Carthage Cartfile:

github "Mapbox/MapboxDirections.swift" ~> 0.8

Or in your CocoaPods Podfile:

pod 'MapboxDirections.swift', :git => 'https://github.com/mapbox/MapboxDirections.swift.git', '~> 0.8'

Then import MapboxDirections or @import MapboxDirections;.

v0.7.0 is the last release of MapboxDirections.swift written in Swift 2.3. The swift2.3 branch corresponds to this release, plus any critical bug fixes that have been applied since. All subsequent releases will be based on the master branch, which is written in Swift 3. The Swift examples below are written in Swift 3; see the swift2.3 branch’s readme for Swift 2.3 examples.

This repository contains example applications written in Swift and Objective-C that demonstrate how to use the framework. To run them, you need to use Carthage 0.19 or above to install the dependencies. More examples and detailed documentation are available in the Mapbox API Documentation.


You’ll need a Mapbox access token in order to use the API. If you’re already using the Mapbox iOS SDK or macOS SDK, MapboxDirections.swift automatically recognizes your access token, as long as you’ve placed it in the MGLMapboxAccessToken key of your application’s Info.plist file.


The main directions class is Directions (in Swift) or MBDirections (in Objective-C or AppleScript). Create a directions object using your access token:

// main.swift
import MapboxDirections

let directions = Directions(accessToken: "<#your access token#>")
// main.m
@import MapboxDirections;

MBDirections *directions = [[MBDirections alloc] initWithAccessToken:@"<#your access token#>"];
-- AppDelegate.applescript
set theDirections to alloc of MBDirections of the current application
tell theDirections to initWithAccessToken:"<#your access token#>"

Alternatively, you can place your access token in the MGLMapboxAccessToken key of your application’s Info.plist file, then use the shared directions object:

// main.swift
let directions = Directions.shared
// main.m
MBDirections *directions = [MBDirections sharedDirections];
-- AppDelegate.applescript
set theDirections to sharedDirections of MBDirections of the current application

With the directions object in hand, construct a RouteOptions or MBRouteOptions object and pass it into the Directions.calculate(_:completionHandler:) method.

// main.swift

let waypoints = [
    Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.9131752, longitude: -77.0324047), name: "Mapbox"),
    Waypoint(coordinate: CLLocationCoordinate2D(latitude: 38.8977, longitude: -77.0365), name: "White House"),
let options = RouteOptions(waypoints: waypoints, profileIdentifier: MBDirectionsProfileIdentifierAutomobile)
options.includesSteps = true

let task = directions.calculate(options) { (waypoints, routes, error) in
    guard error == nil else {
        print("Error calculating directions: \(error!)")

    if let route = routes?.first, let leg = route.legs.first {
        print("Route via \(leg):")

        let distanceFormatter = LengthFormatter()
        let formattedDistance = distanceFormatter.string(fromMeters: route.distance)

        let travelTimeFormatter = DateComponentsFormatter()
        travelTimeFormatter.unitsStyle = .short
        let formattedTravelTime = travelTimeFormatter.string(from: route.expectedTravelTime)

        print("Distance: \(formattedDistance); ETA: \(formattedTravelTime!)")

        for step in leg.steps {
            let formattedDistance = distanceFormatter.string(fromMeters: step.distance)
// main.m

NSArray<MBWaypoint *> *waypoints = @[
    [[MBWaypoint alloc] initWithCoordinate:CLLocationCoordinate2DMake(38.9131752, -77.0324047) coordinateAccuracy:-1 name:@"Mapbox"],
    [[MBWaypoint alloc] initWithCoordinate:CLLocationCoordinate2DMake(38.8977, -77.0365) coordinateAccuracy:-1 name:@"White House"],
MBRouteOptions *options = [[MBRouteOptions alloc] initWithWaypoints:waypoints
options.includesSteps = YES;

NSURLSessionDataTask *task = [directions calculateDirectionsWithOptions:options
                                                      completionHandler:^(NSArray<MBWaypoint *> * _Nullable waypoints,
                                                                          NSArray<MBRoute *> * _Nullable routes,
                                                                          NSError * _Nullable error) {
    if (error) {
        NSLog(@"Error calculating directions: %@", error);

    MBRoute *route = routes.firstObject;
    MBRouteLeg *leg = route.legs.firstObject;
    if (leg) {
        NSLog(@"Route via %@:", leg);

        NSLengthFormatter *distanceFormatter = [[NSLengthFormatter alloc] init];
        NSString *formattedDistance = [distanceFormatter stringFromMeters:leg.distance];

        NSDateComponentsFormatter *travelTimeFormatter = [[NSDateComponentsFormatter alloc] init];
        travelTimeFormatter.unitsStyle = NSDateComponentsFormatterUnitsStyleShort;
        NSString *formattedTravelTime = [travelTimeFormatter stringFromTimeInterval:route.expectedTravelTime];

        NSLog(@"Distance: %@; ETA: %@", formattedDistance, formattedTravelTime);

        for (MBRouteStep *step in leg.steps) {
            NSLog(@"%@", step.instructions);
            NSString *formattedDistance = [distanceFormatter stringFromMeters:step.distance];
            NSLog(@"%@", formattedDistance);
-- AppDelegate.applescript

repeat with theStep in theLeg's steps
    log theStep's instructions
    set theDistance to theDistanceFormatter's stringFromMeters:(theStep's distance)
    log "" & theDistance & ""
end repeat

This library uses version 5 of the Mapbox Directions API by default. To use version 4 instead, replace RouteOptions with RouteOptionsV4 (or MBRouteOptions with MBRouteOptionsV4).

Drawing the route on a map

With the Mapbox iOS SDK or macOS SDK, you can easily draw the route on a map in Swift or Objective-C:

// main.swift

if route.coordinateCount > 0 {
    // Convert the route’s coordinates into a polyline.
    var routeCoordinates = route.coordinates!
    let routeLine = MGLPolyline(coordinates: &routeCoordinates, count: route.coordinateCount)

    // Add the polyline to the map and fit the viewport to the polyline.
    mapView.setVisibleCoordinates(&routeCoordinates, count: route.coordinateCount, edgePadding: .zero, animated: true)
// main.m

if (route.coordinateCount) {
    // Convert the route’s coordinates into a polyline.
    CLLocationCoordinate2D *routeCoordinates = malloc(route.coordinateCount * sizeof(CLLocationCoordinate2D));
    [route getCoordinates:routeCoordinates];
    MGLPolyline *routeLine = [MGLPolyline polylineWithCoordinates:routeCoordinates count:route.coordinateCount];

    // Add the polyline to the map and fit the viewport to the polyline.
    [mapView addAnnotation:routeLine];
    [mapView setVisibleCoordinates:routeCoordinates count:route.coordinateCount edgePadding:UIEdgeInsetsZero animated:YES];

    // Make sure to free this array to avoid leaking memory.


To run the included unit tests, you need to use Carthage 0.19 or above to install the dependencies.
